FOLDING CHAIR.

Application filed March 18, 1925.

To all whom it may concern:

Be it known that I, VVILHELM Rosan- KRANZ, a citizen of the GermanRepublic, residing at Holzminden-on-the-lVeser, Germany, have inventedcertain new and useful Improvements in Folding Chairs, of which thefollowing is a specification.

This invention relates to a folding chair of the kind in which the seatis suspended from the principal frame by means of crank pins which causeit to fold outside the plane of the frame and produce a flat and compactstructure.

The object of the present invention is to produce hinging means of avery simple nature and which can easily be applied, and the inventionconsists in the provision of an S-shaped hinge element, one end memberof which is connected to the frame and the other to the seat, while theintermediate member is recessed into the edge of the seat so as to forma rigid connection with the latter.

Fig. 1 of the accompanying drawings represents a vertical section of thechair in position of use, and t Fig. 2, a similar view of the chair infolded position.

Fig. 3 is a View showing the hinging of the seat to the chair frame, and

Fig. 4, a top View of the corner of the seat to which the hinge-pin isconnected.

5 is a. side view showing a modification of the hinge-pin, and

Fig. 6, a bottom view of the same.

The chair is composed of a principal frame (0 o the upper part of whichforms the back rest and carries for this purpose the necessary latticework a. The lower part of the frame members a constitute the front legsof the chair. A minor frame d which constitutes the rear legs of thechair, is carried across the principal frame so as to support the frontpart of the seat 6 to which it is hinged at 0, the seat being itselfhinged to the principal frame. The frame at is supported on pins a whichar Serial No. 16,539.

connected to the frame members a and which engage longitudinal grooves din the frame members d so as to allow the necessary slidable as well aspivotal relative adjustment for folding and unfolding the chair. A brace(Z connects the lower ends of the frame members (Z.

The seat Z) is, in known manner, hinged to the frame members a so as tobe displaced out of the plane of the latter when it is folded, as shownin Fig. 2. This arrangement allows the seat to clear the back rest sothat it can be folded flat against the latter and easily fastened to theframe members. The fastening of the folded seat to the back rest may beelfect-ed by means of hasps g which are connected to the frame members aand which hook into staples h 05 connected to the edge of the seat.

The hinge elements 6 whereby the seat is connected to the frame membersa are, according to the invention, S-shaped and one end member of eachis in pivotal enside of the seat, as shown in Figs. 5 and 6.

The upper cross-bar of the principal frame is slotted at f to form aconvenient handle for the manipulation of the chair.

I claim:

In a folding chair of the character de- 35 scribed, the combination witha main frame and a seat, of S-shaped hinge elements having one endmember connected to the seat and the other to the frame, the seat beingrecessed to accommodate the intermediate member of the hinge element soas to prevent rotary displacement of the latter relative to the seat.
